Product Details

                                                                                      MZ-97 High Strength Magnesia Brick for Steel Making

 Magnesia Brick

 

Feature:

 

Magnesia brick, Magnesium Oxide content of more than 90%, with the main crystalline phase of periclase. General can be divided into sintered magnesia brick (also called burnt magnesia brick) and chemically bonded magnesia brick (also known as the two major categories of not burned magnesia brick). Purity and high firing temperature of magnesia, due to the direct contact of periclase grains, known as direct bonded magnesite brick; made of fused magnesia bricks called electrically fused magnesite brick.

 

Application:

 

Mainly used for basic open hearth, furnace bottom and furnace wall oxygen converter of steel making, the permanent lining of non-ferrous metal smelting furnace, high temperature tunnel kiln, calcined magnesia brick and cement rotary kiln, furnace bottom and furnace wall, glass furnace regenerator etc.
